California Application & Variants
Mount below the STOP sign and match the message to the uncontrolled approach. This page displays the original LEFT example; the RIGHT design is a separate directional option in the official source. California recommends these plaques where all but one approach has STOP control, unless the non-stopped approach is a one-way street.
